Troopers responded at 11:19 a.m. to 8 Wood Street for a reported shooting inside a home, New York State Police said.

An investigation revealed that a man, identified as Brandon W. Petty, 26, had been in an argument with his sister, Jennifer L. Gravely. During the argument Petty left the room, walked upstairs to a bedroom and returned with a .22-caliber revolver, state police said.

Petty then pointed the revolver at his head, state police said.

When Gravely tried to grab the revolver out of concern, Petty fired a single shot, state police said, which entered his right temple and exited above his right eyebrow. The bullet lodged in the ceiling of the first floor kitchen.

Petty was taken by ambulance to Upstate University Hospital. He is listed in stable condition.
